A Polyglot Approach To Bioinformatics Data Integration: A Phylogenetic Analysis Of Hiv-1, Steven Reisman, Thomas Hatzopoulos, Konstantin Laufer, George K. Thiruvathukal, Catherine Putonti Oct 2017

A Polyglot Approach To Bioinformatics Data Integration: A Phylogenetic Analysis Of Hiv-1, Steven Reisman, Thomas Hatzopoulos, Konstantin Laufer, George K. Thiruvathukal, Catherine Putonti

Konstantin Läufer

As sequencing technologies continue to drop in price and increase in throughput, new challenges emerge for the management and accessibility of genomic sequence data. We have developed a pipeline for facilitating the storage, retrieval, and subsequent analysis of molecular data, integrating both sequence and metadata. Taking a polyglot approach involving multiple languages, libraries, and persistence mechanisms, sequence data can be aggregated from publicly available and local repositories. Data are exposed in the form of a RESTful web service, formatted for easy querying, and retrieved for downstream analyses. As a proof of concept, we have developed a resource for annotated HIV-1 …

Boosting The Performance Of Bayesian Divergence Time Estimation With The Phylogenetic Likelihood Library, Diego Darriba, Andre Aberer, Tomas Flouri, Tracy A. Heath, Fernando Izquierdo-Carrasco, Alexandros Stamatakis Apr 2013

Boosting The Performance Of Bayesian Divergence Time Estimation With The Phylogenetic Likelihood Library, Diego Darriba, Andre Aberer, Tomas Flouri, Tracy A. Heath, Fernando Izquierdo-Carrasco, Alexandros Stamatakis

We present a substantially improved and parallelized version of DPPDiv, a software tool for estimating species divergence times and lineage-specific substitution rates on a fixed tree topology. The improvement is achieved by integrating the DPPDiv code with the Phylogenetic Likelihood Library (PLL), a fast, optimized, and parallelized collection of functions for conducting likelihood computations on phylogenetic trees. We show that, integrating the PLL into a likelihoodbased application is straight-forward since it took the first author (DD) a programming effort of only one month, without having prior knowledge of DPPDiv, nor the PLL. We achieve sequential speedups that range between a …
